Summary
Volvo Car USA LLC and Volvo Car Canada LTD (Volvo) on behalf of Volvo Car Group has decided to launch Recall R29936 on model year 2016 XC90 vehicles. Volvo has identified that the coolant bleeder hose (engine side) may degrade over time and crack due to heat and humidity load. This condition can create a coolant leak, and also pose a risk of coolant leaking on the catalytic converter. If the coolant leak goes unnoticed, coolant may accumulate in the catalytic converter heatshield insulation and, in a worst case scenario, over time this might result in a fire in the engine compartment area when the vehicle is stationary.
